    The color is still white.
    I do remember a water bottle spilling, but that was a long time ago.

You are jumping the gun here. Try first to see if adjusting the contrast will not solve the "problem".

To LIGHTEN screen display.

Turn calculator ON by pressing the ON button.
Press the [2nd] key and release it (Press it just one time)
Press the down arrow and HOLD pressure (keep pressing).
The screen should start lightening up.
Release the Down Arrow when screen contrast is good enough for you.

As to the user manual, it contains no circuit diagram. If you want the manual to learn HOW TO USE the calculator, here is the link.

Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key until the screen lightens.

TI-83 screen is black


The "color" on your screen reset to dark. You can adjust it by pressing "2nd" and the "up" arrow (or "2nd" and "down" arrow) repeatedly.
